Hi All,

I am having problems flashing new firmware onto my SP Racing F3 mini.

I have previously successfully flashed both Cleanflight and Betaflight, but now it does not seem to work.
I know that I have installed some Windows updates since the last successfull flash.

I am running Windows 7 Home Basic.

I can connect to the board successfully in Cleanflight and Betaflight to configure it.

When I try and flash it, when the board goes into DFU mode, Windows comes up with a notification "USB Device Not Recognised".

I have tried in both the Cleanflight and Betaflight GUI.
I have used different USB cables and ports as well.

It appears to be a driver issue, but I have no idea on where to start.

Can someone please help?

TIA.

Have you installed all the drivers?
